I quite like the idea of having the prequel ships looking very different from the OT ones (look at the difference between WWI and WWII) but I don't get why some of the Republic ships look so tatty (it make sense if you are a Rebel or a smuggler but this is meant to be the official government).
I actually like the idea of R2 being blue because he's one of blue group's astrodroids (Naboo seems to be obsessed with aesthetics).
